Passive soaring wings

  • These wing shapes are wide and have slots at the ends.
  • Bald eagles have this wing type. These wings help them catch thermal updrafts and fly for long periods without much flapping.

Active soaring wings

  • These wings are long and narrow.
  • Albatrosses have this wing shape. It helps them fly long distances during migration without using much energy. These wings also help them use horizontal air currents, such as sea breezes.<

Elliptical wings

  • These wings are more rounded and broad. They help birds make quick turns and escape when attacked by predators.
  • Sparrows and turkeys have this wing type. To stay in the air, these birds need to spend a lot of energy because they flap their wings often.

High-speed wings

  • These wings are not as long as passive or active soaring wings, but they are still pointed at the ends. They help birds fly very fast. Like the name implies, high-speed wings are great for rapid movement. However, birds must spend lots of energy flapping to reach high speeds. This makes these wings useful for short bursts of speed, such as chasing flying prey or insects.

Hovering wings

  • Imagine moving your arms backward and forward 80 times in one second! That’s how fast some hummingbirds flap their wings. Their wings are very small and super light.
  • Their muscles are incredibly strong, and their reflexes are very sharp. Did you know they can fly backward too? If you ever get close to these birds, you can hear the sound they make when they flap their wings. It sounds like a high-speed fan. Hummingbirds move their wings in a figure-eight pattern, which helps them hover while drinking nectar from a flower.

Ponder

  • Why do birds have different wing shapes?
  • What can we infer about a bird by looking at its wing shape?
